Hydrodynamic Characteristics of a Butterfly Valve Controlling Al2O3/Water Nanofluid Flow
ABSTRAKT
This paper investigates computationally the reliability of the valve loss coefficient and torque coefficient of butterfly valves when the flow is Al2O3/water nanofluid. The model is constructed and discretized according to five opening angles of 0, 20, 30, 55, and 75°. Three different inlet velocities of 1, 2 and 3 m/s were tested. The study was carried out numerical analysis using commercial CFD code FLUENT. The results revealed that the valve loss and torque coefficients are unreliable in design of the butterfly valves.
